  • the method also may include sealing (by forming the seal over the second liquid) the second liquid in the second sub-chamber and forming a permanent seal that intersects the frangible seal to form a first retaining chamber, a second retaining chamber, a third retaining chamber, and a fourth retaining chamber.
  • the first retaining chamber and the second retaining chamber may retain the first liquid.
  • the third retaining chamber and the fourth retaining chamber may retain the second liquid.
  • Forming the permanent seal may include using the ultrasonic seal forming system. Forming the permanent seal may occur when or while the first liquid and the second liquid are within the pouch.
  • the method also may include providing one or more dispensing valves at a top end of the pouch that is opposite from the bottom end.
  • the first liquid may be a different type of liquid than the second liquid.
  • the frangible seal may be formed between a first side and a second side of the pouch.
  • the permanent seal may be formed between a top end and a bottom end of the pouch.
  • the seal may be non-frangible, and the frangible seal may be orthogonal to the permanent seal.
  • Each of the first retaining chamber and the second retaining chamber may have a first size and a first shape.
  • Each of the third retaining chamber and the fourth retaining chamber may have a second size and a second shape. The first size and the first shape may differ from the second size and the second shape, respectively.
  • embodiments of the present disclosure provide systems and methods for efficiently and effectively forming a multi-chamber liquid-retaining package, such as a pouch.

Abstract

L'invention concerne un procédé de formation d'une poche à chambres multiples comprenant le remplissage d'un premier liquide dans une chambre de la poche à travers une ouverture ; la formation d'un joint cassable au-dessus du premier liquide pour fournir une première sous-chambre ayant le premier liquide et une seconde sous-chambre ouverte au-dessus de la première sous-chambre ; le scellement du premier liquide dans la première sous-chambre ; le remplissage d'un second liquide dans la seconde sous-chambre à travers l'ouverture ; la formation d'un joint d'étanchéité sur le second liquide à l'intérieur de la seconde sous-chambre ; le scellement du second liquide dans la seconde sous-chambre ; et la formation d'un joint d'étanchéité permanent qui coupe le joint cassable pour former une première chambre de retenue, une deuxième chambre de retenue, une troisième chambre de retenue et une quatrième chambre de retenue, la première chambre de retenue et la deuxième chambre de retenue retenant le premier liquide et la troisième chambre de retenue et la quatrième chambre de retenue retenant le second liquide.
